Cygnett announces the US release of its GrooveTooth Talk hands-free speaker system for Bluetooth enabled cell phones including the iPhone 3G. Here is more info:

The GrooveTooth Talk will allow users to converse while they drive without having their iPhone, Blackberry or mobile phone in-hand resulting in safer rides. Featuring noise suppression, echo cancellation and hours of talk-time, users will never be caught without their hands on the wheel and eyes on the road. The GrooveTooth Talk will be available on www.cygnett.com beginning September 1, 2008 with an MSRP of $79.95 US.

This hands-free speaker phone allows users to drive without uncomfortable ear pieces that may block hearing of important traffic noises like emergency vehicles or other warning sounds.
